This paper describes an interactive installation work set in a large dome space. The installation is an audio and physical re-rendition of an interactive writing work. In the original work, the user interacted via keyboard and screen while online. This rendition of the work retains the online interaction, but also places the interaction within a physical space, where the main 'conversation' takes place by the participant-audience speaking through microphones and listening through headphones. The work now also includes voice and SMS input, using speech-to-text and text-to-speech conversion technologies, and audio and displayed text for output. These additions allow the participant-audience to co-author the work while they participate in audible conversation with keyword-triggering characters (bots). Communication in the space can be person-to-computer via microphone, keyboard, and phone; person-to-person via machine and within the physical space; computer-to-computer; and computer-to-person via audio and projected text.

The Distributed Systems Technology Centre (DSTC) framework for workflow specification, verification and management captures workflows transaction-like behavior for long lasting processes. FlowBack is an advanced prototype functionally enhancing an existing workflow management system by providing process backward recovery. It is based on extensive theoretical research ([3],[4],[5],[6],[8],[9]), and its architecture and construction assumptions are product independent. FlowBack clearly demonstrates the extent to which generic backward recovery can be automated and system supported. The provision of a solution for handling exceptional business process behavior requiring backward recovery makes workflow solutions more suitable for a large class of applications, therefore opening up new dimensions within the market. For the demonstration purpose, FlowBack operates with IBM FlowMark, one of the leading workflow products.
